PATENT QFFICEt BAG-HOLDER.

SPECIFICATION forming part of Letters Patent No. 756,693, dated April 5, 1904.

Application filed August 13, 1903. Serial No. 169,383. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD V. PARR, a citizen of the United States, residing at (Jraigsville, in the county of Augusta and State of Virginia, have invented certain new and useful Improvements in Bag-Holders, of which the following is a specification.

The object of my said invention is to provide an improved construction of bag-holders for use in connection with separators or any kind of machine from which any substance is fed into bags, whereby a holder is provided which is simple in its construction, easy to operate, and will exclude dust and all other foreign substance from the sack, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar letters of reference indicate similar parts, Figure 1 is a side elevation of a bag holder of my improved construction as when expanded in use; Fig. 2, a similar view yvith the parts in the position they occupy when the mouth is contracted to receive or permit the removal of the bag, and Fig. 3 a horizontal section looking downwardly from dotted line 3 3 in Fig. 1.

Said bag-holder is constructed, preferably, of sheet metal, but any suitable material may of course be used. It consists of a top A, formed with a neck a, adapted to connect with the delivery-spout of the machine with which the device is to be used, being of suitable size and form for this purpose. Said top is also provided with a downwardly-extending flange around its lower edge, one side, a, of which is tapered inwardly, as shown most clearly in Fig. 2. Part Ais secured by rivets a to the straight side of said flange and extends down a suitable distance for the purpose. A similar part A is mounted around the opposite side of said flange, being pivoted at its upper inside corner on a pivot-rod a which extends through from one side of the device to the other and serves as a brace or support for the top of the device, as well as a pivot for the said hinged part A A bifurcated lever A embraces the hinged section A and is pivoted to the fixed section A on pivots (4*, carried by plates a riveted to the sides of said section.

Shortlinks A* are connected at one end by pivots a with the branches of said lever on each side of the device and at their other ends are connected to the hinged section by pivots a on plates a riveted to the sides of said hinged section. The construction is, in efiect, a toggle-lever, as shown most clearly in Fig. 2.

The parts may be connected reversely to the arrangement above described, if preferred, as indicated by dotted lines in Fig. 3, without changing the operation of the device.

In use, the device being connected with the delivery-spout of the machine with which it is to be used and it being desired to place a bag thereon, the lever A is raised from the position shown in Fig. 1 to that shown in Fig. 2, which through the links A swings the lower end of the hinged section A inwardly on its pivot (o to the position shown in Fig. 2. The mouth of the bag is then placed over the lower end of the device and said lever A pressed downwardly to the position shown in Fig. 1, which straightens the toggle, brings the hinged section to the position shown in Fig. 1, with its sides parallel with the side of the fixed section A, expands the mouth of the device firmly into the mouth of the bag until it is filled, when it may be removed and another substituted in the manner above indicated. By forming the portion a of the lower flange of top A tapered a free movement of the hinged section is permitted. As shown in the drawings, the adjacent edges of the two sections A and A overlap somewhat, so that the device is at all times closed when in use to exclude from the sack all dust and other foreign substance. As indicated in Fig. 3, the device is preferably oval in cross-section with flat sides; but any suitable form preferred may be employed, as will be readily understood.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bag-holder comprising an integral receiving top or hopper, a fixed section secured rigidly to and depending from one side of said top, a hinged section pivoted on the other side of said top with its edges overlapping the edges of the fixed section when parallel there- Ice with, and a lever pivoted at one end to one section and connected by a link to the other section, whereby said pivoted sectionmay be operated to contract and expand the mouth of the device, substantially as set forth.-

2. A bag-holder comprising a top formed with a neck for attachment to the machine and with a lower flange straight on one side and tapered on the other, the fixed section mounted on the straight side of said flange a pivoted section on the other side and a lever pivoted at one end to one section and connected by a link with the other section, substantially set forth.

3. The combination in a bag-holder of a top A provided with the neck a and the flange around its lower edge having a tapered sidev and the links A connected at one end to the branches of said lever and at the other end to the other section, all substantially set forth. In witness whereof I have hereunto set my hand and seal, at Staunton, Virginia, this 3d day of August, A. D. 1903.
